I did the supervised Mensa IQ test some years ago, after scoring in the 130s in the 'school' supervised test, but I didnt make membership after the sup'd one
Out of 1400 or so pupils there was 20 odd who scored in the same 'band' as me and did the supervised test. A few I knew made it into mensa a few I didnt know. One went onto work for BT in its IT departmment, the other went onto work for EA on its game engines after writing one for his uni thesis. Not heard from either for a while tho.
I do remember a bit about one of the tests tho, There was a set of questions on the test that I remember as my mind was just going BLAH, you dummy!
Was something like:
if a bath tub holds 50 liters of water, each of the taps full on fills the bath at 16 liters per minute, the plug when released will allow 22 liters of water minute minute out.
If the bath had 40 liters in it, 1 tap was full on and the plug was out, how long would it take for the bath to empty.
If both taps was on, the bath was empty, and the plug was removed, how would it take to fill up ?
If the plug is out, there is 10 liters in the bath, both taps are on for 30 seconds, the plug is removed, how many liters will be lost before the bath is filled ?
Was stuff like that and mind was just like 'yeah whatever'.
